Vegetative propagation of Piper betle in the central provinces

Abstract

1. Out of the twelve cuttings from each vine the first three took comparatively a longer period for germination than the rest. 2. Mortality due to Phytophthora parasitica var. piperina was highest in 5th to 12th cuttings, the least susceptible being the 3rd cutting. 3. Highest rate of growth was observed in the first cutting with progressively lesser rate in the succeeding ones. 4. Yield of leaves was greatest in the first three cuttings. 5. Incidence of foot-rot disease was significantly minimised when only the first three cuttings from each vine were used for propagation.
